Title: Appareil de pulverisation pour epuration par voie humide et procede d'elimination des oxydes de soufre contenus dans des effluents de combustion
Inventor: DOUGHTY JOSEPH V
IPC: B01D53/18
Filed: 1998-02-26
Abstract: La présente invention concerne un appareil de pulvérisation pour épuration par voie humide et un procédé d'élimination des oxydes de soufre (SO¿x?) contenus dans des effluents de combustion permettant de réaliser des économies en capitaux et en dépenses de fonctionnement grâce à un agencement de tuyaux de têtes de pulvérisation et de buses permettant au service de maintenance d'accéder facilement à un espace réduit (par exemple, 0,5 à 1,25 mètre) situé entre des niveaux de pulvérisation. Dans une zone de pulvérisation, deux niveaux de pulvérisation au moins comprennent une pluralité de tuyaux de têtes de pulvérisation parallèles aux autres tuyaux de têtes de pulvérisation dans un niveau de pulvérisation et verticalement parallèles aux tuyaux de têtes de pulvérisation dans au moins un niveau adjacent de pulvérisation. Chacun des niveaux de pulvérisation comprend une pluralité de buses de pulvérisation qui s'étendent depuis les dites têtes de pulvérisation. On place une majorité de buses dans un niveau de pulvérisation de référence de sorte que des lignes tirées entre elles forment un modèle de carrés, les buses étant situées aux coins des carrés. On place également une majorité de buses d'un niveau de pulvérisation adjacent au-dessus des centres des carrés définis par quatre buses du niveau de pulvérisation de référence. Les autres avantages de la présente l'invention sont l'aptitude à soutenir les têtes de pulvérisation par fixation en treillis de deux têtes adjacentes ensemble dans un agencement auto-porteur ou par fixation par des crochets suspendus verticalement qui ne gênent pas l'accès du service de maintenance.
Patent CA-2281810-A1 (CA)
Title: Improvements relating to electrical surge arresters
Inventor: DOONE RODNEY MEREDITH
IPC: H01C8/04
Filed: 1998-02-25
Abstract: An electrical surge arrester is manufactured by securing a stack of metal oxide varistor blocks between end terminations by passing a rod through through-holes in the varistor blocks and securing the ends of the rod to the end terminations. The through-holes are larger than the rod cross section and a silicone rubber material is injected into the void which otherwise would exist between the rod and the interior surfaces of the through-holes in the varistor blocks. The silicone rubber material is also moulded around the exterior of the stacked varistor blocks and forms a shedded external housing for the arrester. The silicone rubber coatings on the varistor block internal and external surfaces effects a passivation function and means that the passivation coatings normally provided on the surfaces of varistor blocks by their manufacturers at significant cost can be omitted.

Title: Fastener driving device with improved actuating assembly
Inventor: WHITE BRIAN M
IPC: B25C1/04
Filed: 1997-12-05
Abstract: An improved pneumatically operated fastener driving device comprising an actuating assembly (26) mounted with respect to a housing assembly (28) and movable from an inoperative position to an operative position. A first sealing element (110) is mounted with respect to a feed path. The first sealing element moves from a sealed position, wherein it prevents communication between an air pressure reservoir (18) and a control pressure chamber (54) when the actuating assembly (26) is in the operative position, and an unsealed position, wherein the first sealing element (110) permits such communication to move a main valve (36) to a closed position when the actuating assembly (26) is in the inoperative position. A biasing element (88) is operatively associated with the second sealing element (84) and biases the second sealing element towards its unsealed position to maintain communication of the control pressure chamber (54) with the atmosphere until the first sealing element (110) has moved to its unsealed position.

Title: Drilling apparatus
Inventor: EATON MICHAEL ROBERT
IPC: E21B47/12
Filed: 1999-11-16
Abstract: A drilling rig 10 supports a drill string 11 within a borehole 12. An acoustic receiver 14 is associated with a drill bit 13 connected to the end of the drill string 11.  An acoustic source 16, such as an airgun, is located at the earth's surface 17 some distance from the rig 10. In operation, the acoustic source 16 is controlled to transmit an acoustic pulse downwards into the rock formations surrounding the borehole 12. The acoustic energy travelling on a path 18 reaches the rock in contact with the drill bit 13 which is thereby detected by the acoustic receiver 14. Boundaries 20 and 23 in the rock formations are detected and their positions determined by receiving signals from the source 16 after reflection by the boundaries 20 and 23. Time-depth check-shots may be obtained by timing acoustic propagation along either path 18 or path 27. A Vertical Seismic Profile can be obtained by performing measurements with the drill bit 13 at different depths in the borehole.

IPC: B62B1/14
Filed: 2000-10-27
Abstract: This invention relates to an all season mufti-purpose shovel and wheel barrow combination, in the fashion of a human powered mini front end loader. The apparatus is comprised of a multi-medium container for scooping snow, gravels, soils etc. This container (9) is moved along the ground or at varying heights scooping up any loose piled material to be shoveled and transported to another location. The container is attached to a wheeled frame (5,14), which is pushed by handles (3) similar to a wheel barrow, after said frame is rotated to a horizontal position. Upon reaching a destination the container [ shovel or bucket - (9) ] can be dumped efficiently by rotation through the use of dump straps (2). The dump straps are attached to the container dump strap connector bracket (15), and the frame hip thigh push bar (1) at the other end. The container is rotated by pulling the dump strap handle (6), sliding said straps over a directional control cross bar (7). The hinged gravity stop (8) locks the container while in the vertical position to allow filling. When the unit is rotated to the horizontal transport position, the loads center of gravity is transferred to the rear of the container helping balance the unit for increased mechanical advantage.      This shift of weight also trips the hinged gravity stop allowing rotation of the container for dumping. The container is held in place and rotated on two aligned rotation assemblies (10) which are connected to the frame. The re-enforced container forward edge (11) is driven into the material to be transported by pushing on the frame foot push bar area between the wheels (14). Adjustment of the container maximum rear rotation angle, is done with the dump strap buckles (4).
